MPLS VPN

MPLS VPN is a technique that uses Multiprotocol Label Switching to create private, isolated network connections over a shared provider backbone. Service providers use it to offer private WAN connectivity to enterprise customers, where each customer's traffic is logically separated from others, even though it travels across the same physical infrastructure. MPLS VPNs are highly scalable and offer predictable performance, making them a popular choice for connecting multiple branch offices across a wide area network.
